GAS-ESCAPE.

Specification of Letters Patent.

Application filed May 25, 1909.

Patented Nov.- 30, 1909.

Serial No. 498,212.

To all whom it may concern:

Be it known that I, HOMER H. FULTON, a citizen of the United States, anda resident of Oroville, in the county of Butte and State of California,have invented a new and Im proved Gas-Escape, of which the following isa full, clear, and exact description.

The invention is designed to provide an appliance for the escape ofgases from gas, vapor and similar heaters, the appliance beingapplicable to windows of various sizes and easily set up and removed.

To this end the invention in general consists of an extensible windowstopper, a pipe carried by and projecting outwardly from the stopper,with which the flue of the gas or oil heater connects, and a hood spacedfrom and covering the outer end of the pipe.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the vlews.

Figure 1 is a vertical section through a window having my improved gasescape applied thereto; Fig. 2 is a horizontal section on the line 2-2of Fig. l; and Fig. 3 is a cross-section of the stopper on the line 3-3of Fig. 2.

An extensible window stopper designed to close a portion of the windowopening, either above or below the sash, consists of two plates 5 and 5overlapping at their inner ends, at which point the outer plate 5 isprovided with an inwardly pro ecting stud 6 passing through alongitudinal slot 7 in the plate 5 the stud 6 having a thumb nut 8 tobind the two plates together and secure them in any position ofadjustment within the limits afforded by the slot. Both flanges 5 and 5are reinforced at the slot by reinforcing strips 9 and 10 respectively,the strip 9 being riveted or otherwise secured to the outer face of theplate 5, and the strip 10 secured to the inner face of the plate 5 andsimilarly slotted. The bottom and top edges of the outer plate 5 areturned outwardly to form flanges 11 and 12, and the corresponding edgesof the plate 5 are turned inwardly to form flanges 11 and 12 the flanges12 and 12 being located at the top and bottom respectively and incliningdownwardly and outwardly, and the flanges 11 and 11 arranged atright-angles to the plane of the stopper. This construction of theflanges adapts the stopper to seat flat in windows having window sillswith beveled upper faces, as well as in windows in which these faces ofthe window sills are horizontal, as shown in Fig. 1.

The outer end of each plate 5 and 5 is bent at right-angles to the planeof the plate to form a flange 13, and then bent upon itself and extendedto the opposite side of the plate to form a flange 14:, both the flanges13 and 14: being substantially wider than the flanges at the top andbottom edges of the plates, whereby the stopper may be snugly fittedinto sash ways of different widths, by simply bending the edge of theflange 1a outwardly so that the combined width of the flanges 13 and 14is equal to that of the sash groove or way. This construction affordsthe stopper a substantial bearing face at each end, against the windowjambs, and prevents "the stopper from tilting when in place. The plate 5has an opening 15 near or above the longitudinal center of the stopper,over which is secured at the outside a pipe 16 of equal internaldiameter, the pipe having a hood 17 of conical form attached at itsouter end, which is spaced a sufficient distance from the outer edge ofthe pipe to permit of the escape of the gases, as is the usual practicein ventilator construction.

A gas or vapor heater 18, and which I have shown for convenience ofillustration to be in the form of an open fireplace, has a gas or vaporflue 19 which is connected with the pipe 16, thus discharging theobnoxious gases to the outside of the room. If desired, the contactingedges or faces of the stopper may be covered with felt, or other softflexible material, 20, as shown in Fig. 1, to insure a weather-tightfit.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A window stopper comprising plates having overlapping inner endsadjustably secured together, each plate having the outer end portionthereof bent at approximately right-angles to the plane of the stopperand bent upon itself to provide flanges at both the inner and outer sideof the plate to fit in the window sash ways.

2. A window stopper comprising plates having overlapping inner endportions adjustably secured together, each plate having its upper andlower edge turned from the other plate to form flanges, with the uppername to this specification in the presence of and lower flange ofopposlte plates 1ncllnlng two subsorlblng wltnesses.

downwardly and outwardly and the other 1 flanges of the plates arrangedat approxi- HOMER HARVBY B ULrl 5 lnately right-angles to the plane ofthe Witnesses:
